Scientists have discovered the existence of water on both our moon and on Mars. Both findings are significant, but what do they mean? Can we use this information to our advantage for space exploration?

Of course we want to go to Mars. Until we figure it out though, roving robots with names like Spirit, Opportunity, Sojourner and Curiosity are our best bet for digging up dirt on our nearest planetary neighbor. Want to go along for the ride?

Since the 19th century, humans have wondered about the prospect of life on Mars. How is it different from Earth? How is it similar? And could life really have existed there long ago, or exist in the future?

NASA has an SUV-sized rover on Mars, and it’s sending new data back to Earth all the time. Landing Curiosity (and other rovers) on the red planet is no small affair. Check out these pictures of rovers and the extreme engineering that goes into a successful mission.

Until recently, most people assumed that if Mars had liquid water, it no longer did and hadn't for quite some time. But scientists have recently noticed some anomalies in photos of Mars that may suggest there is water. Could there be life, too?
